A visual basic PropertyGrid control displays properties for any object or type and it retrieves the item's properties, primarily using reflection. It provides access to the properties it represents but not in a very friendly way. It holds them in a tree structure. The exact structure depends on whether the user is displaying Items by category or alphabetically.
